Pin holes are drilled in an all-brass shank with a computer programmed drilling machine. This pin-point accuracy allows precision placement of our steel pins. Positive action through the coat when combing is achieved by the use of rounded tip steel pins. They comb smoothly through any dog or cats coat. These all-metal professional series combs are nickel-plated and then a polypropylene handle is molded to the shank. You can count on the teeth staying in and the handle staying on. Black handle for dog combs and red handle for cat (only available in fine spacing) comb.
